      abstract     = {This work combines two powerful self-energy techniques: the
                      well-known GW method and a self-energy recently developed by
                      us that describes renormalization effects caused by the
                      scattering of electrons with magnons and Stoner excitations.
                      This GT self-energy, which is fully k-dependent and contains
                      infinitely many spin-flip ladder diagrams, was shown to have
                      a profound impact on the electronic band structure of Fe,
                      Co, and Ni. In the present work, we refine the method by
                      combining GT with the GW self-energy. The resulting GWT
                      spectral functions exhibit strong lifetime effects and
                      emergent dispersion anomalies. They are in an overall better
                      agreement with experimental spectra than those obtained with
                      GW or GT alone, even showing partial improvements over
                      local-spin-density approximation dynamical mean-field
                      theory. The performed analysis provides a basis for applying
                      the GWT technique to a wider class of magnetic materials.},
